I believe fossil fuels have their place, but will need to be replaced sooner, rather than later. Right now, the highest density energy option for transportation and general bulk power delivery is fossil or nuclear (in the case of grid-based energy delivery.) Using renewables is going to require a massive change in how the energy infrastructure is designed, including automobiles. The grid is perfectly capable of handing charge dumps right now, but as the balance shifts more towards EVs and renewables, something has to give. It's going to be your car. You don't easily replace a 1.6GW coal plant. That should be clarified a bit. The highest density, easily obtained would be a better wording.
